扫描文档，自定义布局，另存为PDF文件。
This "Pro" version doesn't add any watermark to the generated PDF files. All features are the same in free version and Pro version.
Scan documents, customize the layout, save as a PDF file.
Perfect for receipt scanning, once scanned you can crop the image, optimize the contrast.
Trick: during cropping, when an anchor is selected (with magnified view), slide your finger anywhere on the picture (not on the magnify) to move the anchor with precision.
